◆ beginFragment()

virtual void llvm::AsmPrinterHandler::beginFragment	(	const MachineBasicBlock *	MBB,
		ExceptionSymbolProvider	ESP
	)

inlinevirtual

Reimplemented in llvm::DwarfCFIException.

Definition at line 57 of file AsmPrinterHandler.h.

◆ beginFunclet()

virtual void llvm::AsmPrinterHandler::beginFunclet	(	const MachineBasicBlock &	MBB,
		MCSymbol *	Sym = `nullptr`
	)

inlinevirtual

Emit target-specific EH funclet machinery.

Reimplemented in llvm::WinException.

Definition at line 62 of file AsmPrinterHandler.h.

◆ beginFunction()

virtual void llvm::AsmPrinterHandler::beginFunction ( const MachineFunction * MF )

pure virtual

Gather pre-function debug information.

Every beginFunction(MF) call should be followed by an endFunction(MF) call.

Implemented in llvm::DebugHandlerBase, llvm::WinException, llvm::ARMException, llvm::DwarfCFIException, llvm::WinCFGuard, and llvm::WasmException.

◆ beginInstruction()

virtual void llvm::AsmPrinterHandler::beginInstruction ( const MachineInstr * MI )

pure virtual

Process beginning of an instruction.

Implemented in llvm::DwarfDebug, llvm::CodeViewDebug, llvm::BTFDebug, llvm::EHStreamer, llvm::DebugHandlerBase, and llvm::WinCFGuard.

Referenced by endFunclet().

◆ endFragment()

virtual void llvm::AsmPrinterHandler::endFragment ( )

inlinevirtual

Reimplemented in llvm::DwarfCFIExceptionBase.

Definition at line 59 of file AsmPrinterHandler.h.

◆ endFunclet()

virtual void llvm::AsmPrinterHandler::endFunclet ( )

inlinevirtual

Reimplemented in llvm::WinException.

Definition at line 64 of file AsmPrinterHandler.h.

References beginInstruction(), endInstruction(), and MI.

◆ endFunction()

virtual void llvm::AsmPrinterHandler::endFunction ( const MachineFunction * MF )

pure virtual

Gather post-function debug information.

Please note that some AsmPrinter implementations may not call beginFunction at all.

Implemented in llvm::DebugHandlerBase, llvm::WinException, llvm::ARMException, llvm::DwarfCFIException, llvm::WinCFGuard, and llvm::WasmException.

◆ endInstruction()

virtual void llvm::AsmPrinterHandler::endInstruction ( )

pure virtual

Process end of an instruction.

Implemented in llvm::EHStreamer, llvm::DebugHandlerBase, and llvm::WinCFGuard.

Referenced by endFunclet().

◆ endModule()

virtual void llvm::AsmPrinterHandler::endModule ( )

pure virtual

Emit all sections that should come after the content.

Implemented in llvm::DwarfDebug, llvm::CodeViewDebug, llvm::BTFDebug, llvm::WinException, llvm::ARMException, llvm::DwarfCFIException, llvm::WinCFGuard, and llvm::WasmException.

◆ markFunctionEnd()

void AsmPrinterHandler::markFunctionEnd ( )

virtual

Reimplemented in llvm::DwarfCFIExceptionBase, and llvm::WasmException.

Definition at line 3050 of file AsmPrinter.cpp.

◆ setSymbolSize()

virtual void llvm::AsmPrinterHandler::setSymbolSize	(	const MCSymbol *	Sym,
		uint64_t	Size
	)

pure virtual

For symbols that have a size designated (e.g.

common symbols), this tracks that size.

Implemented in llvm::DwarfDebug, llvm::CodeViewDebug, llvm::BTFDebug, llvm::EHStreamer, and llvm::WinCFGuard.
